The following is exothermic or endothermic"The combustion of gasoline in a car engine?
Gas
Which of the following is an example of an exothermic reaction?
does it matter? an exothermic reaction has heat as a biproduct of the product while an endothermic reaction has heat as a part of the reactants. meaning heat is released in exothermic and absorbed in endothermic
Witch of the following phase changes is an exothermic change?
An exothermic phase change is one that releases heat to the surroundings. Among common phase changes, freezing (liquid to solid) and condensation (gas to liquid) are exothermic processes. During these changes, energy is released as the substance transitions to a more stable state.
Which of the following examples involves an exothermic change?
Examples for exothermic change are burning of fuels or coal, burning of a fire cracker and glowing of an electric lamp.
Can you Classify the following reactions as exothermic or endothermic?
Sure! To classify a reaction as exothermic or endothermic, you need to consider whether it releases or absorbs heat. An exothermic reaction releases energy to the surroundings, typically in the form of heat, causing a temperature increase. An endothermic reaction, on the other hand, absorbs energy from the surroundings, resulting in a temperature decrease. If you provide specific reactions, I can help classify them accordingly.
What happens when Hydrochloric acid reacts with ammonium hydroxide is this a exotheermic or endothermic?
HCl + NH3 --> NH4Cl is already exothermic Ammonium hydroxide is the solution of NH3 in water, giving the following exothermic reaction: [NH4OH]aq + H+aq + Cl-aq --> NH4+aq + H2Oliq + Cl-aq
Among the DOT Division 4.1 which of the following are liable to undergo at normal or elevated temeratures a strongly exothermic decomposition caused by excessively high transport temperatures or by?
Self reactive material
Which of the following best describes H2 g Cl2 g 2HCl g H 184.6 kJ mol?
The reaction produces heat.
Which of the following is or are exothermic 1. the reaction of butane with oxygen 2.melting of gold 3.cooling of copper from 225c to 65c?
The reaction of butane with oxygen is exothermic as it releases energy in the form of heat. The melting of gold is an endothermic process as it absorbs heat energy to break intermolecular forces and change the state from solid to liquid. The cooling of copper from 225°C to 65°C is an exothermic process as heat is released to the surroundings during the cooling.
What is the exothermic chemical reaction for lithium and water?
The exothermic chemical reaction between lithium and water can be represented by the following equation: 2Li(s) + 2H₂O(l) → 2LiOH(aq) + H₂(g) + heat. This reaction produces lithium hydroxide, hydrogen gas, and heat energy.
Which of the following describes an exothermic reaction A. ht reactants equals 0 B. ht reactants ht products C. ht equals ht D. ht ht?
Hf, reactants > Hf, products apex
How will you indicate following effects in a chemical reaction a solution made in water exothermic and endothermic reaction?
In an exothermic reaction, the solution will release heat, resulting in a noticeable increase in temperature, which can be felt by touch or measured with a thermometer. Conversely, in an endothermic reaction, the solution will absorb heat from its surroundings, leading to a decrease in temperature, often causing the solution to feel cold. Both effects can be visually indicated through temperature changes observed during the reaction.
